Is there a more common plant in the Four Corners? Yarrow’s fern-like leaves, which have a strong, pleasant, distinctive smell, often carpet meadows and woods.  Of these masses of plants, few produce flowers, but because Yarrow is so prolific there are still many flowers.  A close look at the flower often surprises, for it shows Yarrow to be a Sunflower with both ray and disk flowers. (See below.)  The dried flowers are long-lasting and are often gathered for household displays.

Achilles is believed to have discovered the medicinal uses of this plant for healing wounds.  "Lanulosa" is Latin for "wooly".

Yarrow spreads from stout roots and large patches of the fern-like basal leaves are a very common sight around mountain homes, meadows, and woodlands.
